Airtac JSI Series Standard Cylinder JSI100X75
The AirTAC Airtac JSI Series Standard Cylinder JSI100X75 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSI Series Standard Cylinder JSI100X75
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder is built for heavy-duty automation. Its extruded hard-anodized aluminum barrel omits external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore to save valuable machine space. The two-way piston seal retains grease for a long, low-friction service life.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. For sizing, plan for about 2356 N of real work at 0.5 MPa (60 percent of the rated push), which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The unit features a G1/2 port and a 32 mm hard-chrome rod.

Where the Airtac JSI Series Standard Cylinder JSI100X75 Is Used
Stamping Press Feed
Drives heavy metal blanks into a forming die using its 3927 N push force at 0.5 MPa, ensuring consistent placement in automotive part production.
Pallet Squarer
Pushes misaligned pallets square on a high-speed packaging line, utilizing the compact JIS profile to fit within tight conveyor framework.
Injection Mold Ejector
Provides robust ejection force to release dense plastic components from molds, benefiting from the grease-retaining two-way piston seal for continuous cycling.
Is the Airtac JSI Series Standard Cylinder JSI100X75 the Right Cylinder?
When sizing this 100 mm bore, verify if the 80 mm class (providing 2513 N push at 0.5 MPa) is sufficient, or if you need to step up to the 125 mm bore (6136 N push at 0.5 MPa) for heavier demands. You can mount this actuator using LB foot, FA/FB flange, CA/CB/CR clevis, or TC/TCM1/TCM2 trunnion brackets, alongside I, Y, F, or U rod knuckles.
Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 33 mm air cushions only decelerate the piston near stroke end and do not act as a brake. To hold a suspended load securely, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSI Series Standard Cylinder JSI100X75 FAQ
The JSI100X75 delivers a push of 3927 N and a pull of 3574 N at 0.5 MPa, and a push of 5497 N / pull of 5003 N at 0.7 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port and operates at speeds between 30-800 mm/s.
No, this specific SKU does not include a magnet, so it cannot accept CMSE or DMSE magnetic switches. You must order the -S variant (JSI100X75-S) to enable sensor grooves for position feedback.
